Legal Research Toolkit
Separate current web context from legal authority.
Descrybe provides the research capabilities. Perplexity provides the environment where you ask, refine, and use the result.
Check what supports the answer
Resolve citations, retrieve focused source passages, verify quoted language, and inspect the authorities behind the analysis.
Review treatment and citing cases
Research how later courts have treated an authority and find the citing decisions that matter to the issue.
Legal workflow ideas
Ask for the outcome—not just a case search.
These examples show what becomes possible when the surrounding assistant or application combines its own reading, reasoning, and work-product capabilities with focused Descrybe tools. They are ideas for use rather than separate product modes; the exact sequence and available steps depend on the host, its settings, and the context you choose to provide.
Everyday idea
Separate web context from legal authority
Use Perplexity for current public context and Descrybe for focused primary-law research, keeping the legal authorities distinct from general web sources.

Resolve a case mentioned on the web
Start with a party name, short citation, docket number, quotation, or incomplete reference and ask Descrybe to identify the likely case and retrieve its details.

Run a focused authority update
Take a known case from a report or article, review its treatment, locate later citing decisions, and inspect the passages that matter to the current issue.

Compare quoted legal language found in a web source with the underlying opinion and retrieve the case PDF for final inspection.

How it fits your work
Keep Descrybe available from the start of the chat.
- Add Descrybe Legal Engine through Perplexity’s custom connector flow.
- Start a new chat with Descrybe selected so the research tools are available for the first question.
- Check the returned authorities and source material instead of treating the generated answer as the final word.
Perplexity access with custom connectors is separate from your Descrybe subscription.
